WebAccording to Einstein's theory, the energy of a photon is. Question options: 1) proportional to its wavelength. 2) proportional to its frequency. 3) constant, since the speed of light is a constant. 4) quantized, since it always appears in bundles of size, 1.6 ´ 10-19 C. 5) proportional to the square of the frequency. Fizeau was born in Paris to Louis and Beatrice Fizeau. He married into the de Jussieu botanical family. His earliest work was concerned with improvements in photographic processes. Following suggestions by François Arago, Léon Foucault and Fizeau collaborated in a series of investigations on the interference of light and heat.
